TENT VENTILATOR.

Application filed September 1, 1921. Serial No. 497,468.

To all whom it may concern Be it known that I, lViLLIAM T. RUNcIn, a citizen of the UnitedStates, and a resident of Maplewood, llssex County,'l-lew Jersey, have invented a new and useful improve-- ment in Tent Ventilators, of which the following is a full, clear, and-exact description.

My invention relates to improvements in ventilators fortents. Tents as usually made have a very unsatisfactory means of ventilation. Generally they are provided with a top openin through the peak, and a cover strip which can be made to cover the opening in any weather, and which generally has to be manipulated from outside the tent. This is unsatisfactory because a person will often get wet in trying to cover the opening, and if rain comes up suddenly, water will enter through the top. My invention is intended to produce an exceedingly simplev and convenient ventilating attachment which can be applied to many forms of tents, and which can be operated conveniently from inside the tent, so as to open the ventilator to any desired extent for the circulation of air, and which when open will shield the tent opening so as to exclude water. My invention is also intended to provide a structure of this kind which, because of its simplicity, is inexpensive, and which can be readily applied to tents of ordinary structure without changing the tent formation. In the accompanying drawings 1 have shown the ventilator attachment sliding on a tent pole of an ordinary peak-top tent, butit will be understood that the form of the device can be changed to suit tents of diiferent kinds. This will be better understood from the description which follows. I

Reference is to be had to the accompanying drawings forming a part of thisspecification, in which similar reference characters indicate corresponding parts in all the views.

Figure 1 is a broken plan view of a tent provided with my improved ventilator.

Figure 2 is a vertical section on the line 2-2 of Figure 1, showing the ventilator slightly open.

Figure 3 is a view similarto Figure 2, but with the ventilator open to a greater extent, and

Figure 4 shows the application of the ventilator to another form of tent.

The drawings are shown by way of example to illustrate the structure and application of my improved Ventilator, but with out the idea of limiting the invention to the particular structure shown, as it will be understood from the following description that many of the details can be changed without affecting. the invent-ion.

As illustrated, the tent top 10 is supported as usual on a central pole 11, which can be of any preferred kind, and which has a rod 12 extending. from' the top, this being precisely as usual exceptgthat where my ventilator is used, the rod may be a little longer than is customary. Q

The tent top is provided with an opening 13 at its apex, and the top edges around the opening can be connected with the pole by a chain 14 extending to the disk 145 on the pole top, or any convenient means of attachment, this particular feature not entering into my invention, at least as to its detail. As a means of operating the ventilator,' 1 employ a sliding bracket which can be of many forms, but which as illustrated has a vertical rod 15 connecting at the lower end with a ring 16 which slides on the pole 11, and at the top end with the ring 17 of smaller diameter which slides on the rod 12,

theserings 16 and 17 being at right angles to the rod 15, and the parts 15, 16 and 17 constituting the sliding bracket. The upper end of the bracket supports the ventilator cap 18, which is preferably reinforced aroundvthc lower edge as shown at 18 to give it the desired shape and weight, and

which has a" central opening extending through the cap and through the reinforcement 19 around the centre thereof. If reinforcing rod is of other shape than circular it can be jointed at the corners to enable it to fold nicely.

The cap 18 is of a generally conical or pyramidal shape so as to fit over the top of the tent and close the opening 13, and obviously the cross sectional shape of the cap will conform to the cross sectional shape of the tent top. The cap 18 has a flexible con-' nection at its lower edge as shown at 20, with the top of the pole or with the tent top, this connection being at any convenient place, and as shown the drawing illustrates small chains 20 connecting with the disc 14. Ohviously any flexible connection suitable for the purpose can be made between the lower edge of the cap 18 and an adjacent part of the tent or pole to keep the cap from swinging around or being displaced.

By reference to Figures 2 and 3 it will be seen that the bracket carrying the cap 18 can be moved up or down to any desired extent within reasonable limits, so as to leave an air outlet through the opening 13, and between the cap 18 and the tent top, and it will also be noticed that when the cap is raised to provide for ventilation, it permits a free circulation of air, but also excludes water. At the same time the cap is stayed so that it is not liable tobe disarranged or blown away.

The bracket carrying the ventilator cap can be manipulated in various ways, and I have shown a simple means in which a cord 21 connects with the ring 1'6 and runs over a pulley 23 on the upper part of the pole. Thus by pulling down on the cord, the bracket 15, 16, 17, is raised, and the cap 18 With it, thus providing for ventilation, and if the corn is released, the cap 18 drops bygravity.

It will be seen that the device which I have illustrated can be applied to ordinarytents having openings in the top, and that the means for holding the cap in place, for raising and lowering it, and the form of the bracket which carries it, can be changed without affecting the invention in any way. The application of the device does not interfere with the erection of the tent, as the bracket carrying the cap 18 is slipped onto the pole end, the pole thrust through the opening 13 and disk 1 1 and connected with the edge of the tent opening, andthe ring 17, cap 18, and reinforcement 19 slipped over the rod 12, when the pole can be pushed up us usual carrying the tent top and ventilator cap with it.

In Figures 1 to 8 I have shown the application of the ventilator to an ordinary canvas tent, but obviously it can be adapted to tents of various kinds. For instance, in Figure 4 l have shown a framework 25 for the roof which can be covered in any usual way, which has the opening 13 in the top, and has a cross piece 26 supporting a short pole 11 with an extension 12, and the cap 18 can be operated on this as already described.

t will be further observed that this attachment provides for a very simple and perfect ventilation of the tent, and permits the escape of the dead air, heat, smoke, etc, which are very apt to accumulate therein.

1 claim l. A tent ventilator comprising a tent having an opening in the top, a pole for the tent having a reduced extension extending upward through the opening, a bracket having one end sliding on the body of the pole and the other end sliding on the reduced extension, a cap connected with the bracket and arranged above the tent top and shaped to fit over the opening in said top, flexible coniections between the lower edge of the top.

and a fixed part of the structure to prevent the rotation and distortion of said cap, and means for raising and lowering the bracket and cap.

2. A tent ventilator comprising a tent having an opening in the top, a pole for the tent extending upward into and through the said opening, a bracket sliding on the pole and projecting above the tent opening, a cap shaped to fit the tent top and having its middle portion arranged to slide on the pole and connected to the upper part of the aforesaid bracket, and flexible connections between the lower and outer parts of the cap and the fixed part of the structure to prevent the rotation and distortion of the cap.

3. A tent ventilator comprising a tent having an opening through the top, a pole extending upward into and through the aforesaid opening, a bracket slidable on the pole and extending through the said tent opening, means for raising and lowering the bracket, a cap shaped to conform to the tent top and having its middle portion attached to the upper end of the bracket and its lower edge adapted to overlap the tent/top around said opening, and flexible connections between the lower edge of the cap and a fixed part of the pole to prevent the distortion and rotation of the. cap.
